 TorBrowser currently provides "1000x600x24" as arbitrary values for screen
 size. According to
 [[https://panopticlick.eff.org/index.php?action=log&js=yes|Panopticlick]],
 this corresponds to 1 in 439 browsers. A more common value would be
 "1366x768x24" which corresponds to 1 in 16 browsers.

 I am confident that changing the reported screen size to a more common
 value would be a (slight) anonymity improvement for individual users
 (since using the most ubiquitious values across all browsers makes
 distinguishing between them more difficult), However I cannot claim to
 know all the implications (like perhaps using different values between
 different TorBrowser versions would have negative anonymity implications
 for users of the new version, for example).

 I imagine the screen size of 1000x600x24 is going to become less and less
 common as time goes on, so I would advocate chaning to the more
 ubiquitious value sooner rather than later.
